论文摘要
在这项研究中，我们对具有宏观不均匀性的无限超导板中的磁感应，电流密度和温度的空间和时间变化进行数值计算。我们还考虑了高t $ _C $单晶的特征性磁热特性，将同元超导体建模为参照材料。理论形式主义被封闭在动态状态和连续的电动力学方法中。特别是，我们研究了通过随机电流能力的空间轮廓建模的磁跳和温度上升的发生与存在宏观不均匀性之间的相关性。
In this study we perform numerical calculations of the spatial and time variation of the magnetic induction, current density and temperature in an infinite superconducting slab with macroscopic inhomogeneities. We also modeled an homogeneuos superconductor as a referential material, considering characteristic magnetothermal properties of a high-T$_c$ single crystal. The theoretical formalism is enclosed in the dynamical regime and a continuum electrodynamic approach. In particular, we studied the correlation between the magnetic jumps and temperature rise occurrence with the presence of macroscopical inhomogeneities, modeled through an stochastic current-carrying ability spatial profile.
